TROUBLESHOOTING GUIDE:
Problem: When I insert this in line, I don’t observe any gain in reception.
Solution: There are several causes to the problem, but the major one is that
the preamp has been assembled incorrectly. Check Q1 for correct installation,
then check J3 for 12VDC. If those check out, go through assembly steps again
to make sure you have the parts where they belong.
Problem: I can’t get the @#*%! thing to work, it’s Ramsey’s fault!
Solution: Read the warranty information on the next page.
